What does the .83 A/R ratio mean for my turbo's performance?

The .83 A/R (Area/Radius) ratio influences how quickly your turbocharger spools up and where its power band is. A .83 A/R generally provides a good balance, offering quicker spool for better low-end response while still supporting strong mid-range and top-end power.

What is the advantage of a V-band outlet compared to a standard flange?

A V-band outlet uses a clamp system to secure the downpipe to the turbine housing. This design creates a very strong, leak-free seal and can make installation and removal easier compared to traditional bolt-on flanges.

What is a 'reverse rotation' turbocharger?

A reverse rotation turbocharger spins in the opposite direction of a standard turbo. This is typically used in specific twin-turbo setups or custom applications where the engine configuration requires the turbine wheel to spin counter-clockwise. It's crucial to match the housing to your turbo's specific rotation.

About this part

Product Details

This is the Garrett G35 Turbine Housing Kit, specifically designed for reverse rotation applications with a T3 inlet and V-band outlet. The housing features a .83 A/R (Area/Radius) ratio, which is a key factor in determining how quickly your turbocharger spools up and where its power band sits. A .83 A/R generally offers a good balance, allowing for strong mid-range power and a decent top-end pull without excessive lag, making it a popular choice for many performance builds.

Garrett is well-known for its turbocharger technology, and this housing is built to their standards. It's constructed from a durable cast iron material, chosen for its ability to withstand the high temperatures and pressures found in the exhaust stream of a performance engine. The T3 inlet flange is a common size, making it compatible with a wide range of turbo manifolds, while the V-band outlet provides a secure and leak-free connection to your exhaust downpipe. This kit includes the necessary components for installation, ensuring you have what you need to integrate it into your existing turbo system.

When considering a turbine housing upgrade, the A/R ratio is critical. A smaller A/R (like this .83) will typically result in faster spool-up, meaning your engine reaches peak boost pressure sooner. Conversely, a larger A/R will allow the turbo to breathe better at higher RPMs, potentially increasing peak horsepower but at the cost of some initial lag. This particular housing is intended for reverse rotation turbos, which is important for specific twin-turbo setups or unique engine configurations where the direction of the turbine wheel's spin needs to be opposite of standard. Always confirm your turbocharger's rotation direction before ordering.
